Milk on my macbook air?

so my dad wanted to see my macbook air cause we just got it and i was drinking milk. we were on the dinner table when he asked if he could have a lil bit of my milk. so i gave him some. and he dropped it on my air!!!!! i panicked and quickly powered it off and grabbed the computer and put it upside down so all the milk can drain out. i was so mad that i went of for a jog. when i got back i decided to turn it on... and i did it worked fine. its been a year since the milk incidence and my computer is still fine! isnt my computer supposed to be something is wrong with it? also my computer became a little bit slower but its not bad that i complain all the time!!!
